Turbos on semi trucks greatly vary in size, so much so that it can be difficult to quantify just how big they are. Turbos are essentially a type of compressor that helps increase the efficiency and power output of an engine. Semi trucks use them to increase their power output, allowing them to haul heavier loads with less effort.
Turbochargers come in a variety of sizes, depending on the type of engine and the manufacturer. The size of the turbo will determine how much air can be compressed, and therefore how much power can be generated. Generally speaking, a larger turbocharger will provide more power than a smaller one, but this comes at the expense of fuel efficiency.
The size of the turbo is usually determined by its compressor wheel diameter and its turbine wheel diameter. The compressor wheel diameter is typically between 2-4 inches and the turbine wheel diameter is usually between 1-2 inches. The larger the wheel diameter, the more air can be compressed into the engine and therefore more power can be generated.
A large semi truck might require a turbo with a compressor wheel diameter of 3-4 inches and a turbine wheel diameter of 1-2 inches. On the other hand, small pickup trucks may only require a turbo with a compressor wheel diameter of 2-3 inches and a turbine wheel diameter of 1 inch or less.
The size and capacity of turbos on semi trucks also depends on their make and model year. Newer models tend to have larger turbos than older models due to advancements in technology over time. Different types of engines also require different turbos based on their specific requirements for fuel efficiency or power output.
Overall, there is no definitive answer to “How big is a turbo on a semi truck?” as it varies depending on many factors such as the type of engine, manufacturer, model year, etc.. However, generally speaking most semi truck turbos range from 2-4 inches in terms of compressor wheel diameter and 1-2 inches in terms of turbine wheel diameter.
Conclusion:
In conclusion, while there is no definitive answer as to how big a turbo is on a semi truck due to many variables such as engine type, manufacturer, model year etc., most commercial semi truck turbos range from 2-4 inches in terms of compressor wheel diameter and 1-2 inches for turbine wheel diameter.
